Simultaneous somatic (black traces) and non-axon-bearing dendritic (blue traces) recordings of the impact of somatic and dendritic sEPSPs generated at depolarized and hyperpolarized membrane potentials (indicated). Families of sEPSPs were generated in response to incremental series of current waveforms, and threshold responses are delineated by the colored traces. Note the dramatic disparity in the current threshold between somatic and dendritic sites at the hyperpolarized membrane potential. AP waveforms, the morphology of the recorded rat CIN, and the placement of recording electrodes are inset.
